Crawl Space Humidity Help

Thanks everyone, I appreciate all the help, advice and suggestions. I have some phone calls to make asap. I'll be sure to update the post as I get more information on the situation and if I have any more questions.

It looks like a sump pit, not a sinkhole.

Hi Chad.

Are you talking about both holes? The one picture by itself is a second hole. I thought that one might have looked like a sump pit, but the other pictures that show the larger hole seems a bit deep and irregular shape. Do you think it could have been a sump pit and fallen apart over time?

Thanks

It is partly beacuse the water table is often too high. The best fix is add about one square foot of net free crawlspace vent area for wvwry 150 sq.ft of crawlspace are(if no plastic is laid on ground)
